When you are installing the AGP card, please make sure the following notice is fully under-
stood and practiced. If your AGP card has "AGP 4X/8X (1.5V) notch" (show below), please
make sure your AGP card is AGP 4X/8X.
Caution: AGP 2X card is not supported by SiS 760. You might experience system
unable to boot up normally. Please insert an AGP 4X/8X card.

Prepare your computer...
Computer motherboards and expansion cards contain very delicate Integrated Circuit (IC) chips. To
protect them against damage from static electricity, you should follow some precautions whenever you
work on your computer.
1. Unplug your computer when working on the inside.
2. Use a grounded wrist strap before handling computer components. If you do not have one,
touch both of your hands to a safely grounded object or to a metal object, such as the power
supply case.
3. Hold components by the edges and try not touch the IC chips, leads or connectors, or other
components.
4. Place components on a grounded antistatic pad or on the bag that came with the components
whenever the components are separated from the system.
5. Ensure that theATX power supply is switched off before you plug in or remove the ATX power
connector on the motherboard.
Installing the motherboard to the chassis...
If the motherboard has mounting holes, but they don't line up with the holes on the base and there
are no slots to attach the spacers, do not become alarmed you can still attach the spacers to the
mounting holes. Just cut the bottom portion of the spacers (the spacer may be a little hard to cut off, so
be careful of your hands). In this way you can still attach the motherboard to the base without worrying
about short circuits. Sometimes you may need to use the plastic springs to isolate the screw from the
motherboard PCB surface, because the circuit wire may be near by the hole. Be careful, don't let the
screw contact any printed circuit write or parts on the PCB that are near the fixing hole, otherwise it
may damage the board or cause board malfunctioning.

Please set the CPU host frequency in accordance with your processor's specifications.
We don't recommend you to set the system bus frequency over the CPU's specification because
these specific bus frequencies are not the standard specifications for CPU, chipset and most of the
peripherals. Whether your system can run under these specific bus frequencies properly will
depend on your hardware configurations, including CPU, Chipsets, Memory, Cards…etc.

Step1-1.Processorinsertion
Step1-2.Applyingthermalgrease
Step1-3.Coolingfanattachment
Step1-4.Connectingprocessorfanpower
Beforeinstallingtheprocessorandcoolingfan,adheretothefollowingwarning:
1. Theprocessorwilloverheatwithouttheheatsinkand/orfan,resultinginpermanent
irreparabledamage.
2. Neverforcetheprocessorintothesocket.
3. Applythermalgreasebetweentheprocessorandcoolingfan.

5. IfyoudonotmatchtheCPUsocketPin1andCPUcutedgewell,itwillcauseimproper

fan.
Step1-1. First, check the processor pins to see that none are bent. Move the socket lever to the
unlocked position as shown in Figure 1 & Figure 2.(90oto the plane of the motherboard) prior
to inserting the processor. The A1 pin location is designated on the processor by a copper
triangle that matches up to a triangle on the socket as shown in Figure 3. Align the processor
to the socket and gently lower it into place. Do not force the processor into the socket.
Figure 1. Angling the rod to 65-degree maybe feel a
kind of tight , and then continue pull the rod to 90-
degree when a noise "cough" made.
Figure2. Pull the rod to the 90-degree directly.

Step1-2. When the processor is installed in the socket, apply thermal grease to the processor (as
shown in Figure 4) prior to installing the heatsink. AMD recommends using a high thermal
conductivity grease (such as Shin-Etsu types G751 or G749, or an equivalent product) for
the thermal interface material rather than a phase change material. Phase change materials
develop strong adhesive forces between the heatsink and processor.
Removing the heatsink under such conditions can cause the processor to be
removed from the socket without moving the socket lever to the unlocked
position and then damage the processor pins or socket contacts.
** We recommend you to apply the thermal tape to provide better heat conduction between your
CPU and heatsink. (The CPU cooling fan might stick to the CPU due to the hardening of the
thermal paste. During this condition if you try to remove the cooling fan, you might pull the
processor out of the CPU socket alone with the cooling fan, and might damage the processor.
To avoid this from happening, we suggest you to either use thermal tape instead of thermal
paste, or remove the cooling fan with extreme caution.)
Figure 4. Application of Thermal Grease to the processor.
Step 1-4. Connect the fan power wires to the header on the motherboard as shown in Figure 7.
Figure 7. Connecting the Fan Power Wires
Step 1-3.Once the thermal grease has been applied to the processor, the heatsink can be attached to
the processor. Align the heatsink assembly with the support frame mating with the backer
plate standoffs as shown in Figure 5&6.

Before installing the memory modules, adhere to the following warning:
1.Please note that the DIMM module can only fit in one direction due to
the notch. Wrong orientation will cause improper installation. Please
change the insert orientation.
Step 2: Install Memory Modules
The motherboard has 2 dual inline memory module (DIMM) sockets. The BIOS will automatically
detects memory type and size. To install the memory module, just push it vertically into the DIMM
socket. The DIMM module can only fit in one direction due to the notch. Memory size can vary
betweensockets.

DDR Introduction
Established on the existing SDRAM infrastructure, DDR (Double Data Rate) memory is a high
performance and cost-effective solution that allows easy adoption for memory vendors, OEMs, and
system integrators.
DDR memory is a great evolutionary solution for the PC industry that builds on the existing
SDRAMarchitecture,yetmaketheawesomeadvancesinsolvingthesystemperformancebottleneck
bydoublingthememorybandwidth. Nowadays,withthehighestbandwidthof3.2GB/s ofDDR400
memory and complete line of DDR400/333/266/200 memory solutions, DDR memory is the best
choiceforbuildinghighperformanceandlowlatencyDRAMsubsystemthataresuitableforservers,
workstations,andfullrangeofdesktopPCs.
1. The DIMM socket has a notch, so the DIMM memory
module can only fit in one direction.
2. Insert the DIMM memory module vertically into the DIMM
socket. Then push it down.
3. Close the plastic clip at both edges of the DIMM sockets
to lock the DIMM module.
Reverse the installation steps when you wish to remove
the DIMM module.
